Encoder Disconnection Error

What does E80. mean?

This fault is detected if the motor's actual rotation speed (feedback from the encoder) remains below the 'Starting Frequency' (b082) for a duration longer than the 'Encoder Disconnection Detection Time' (P077), while the output frequency is at or above 'Creep Speed Setting' (P015). This suggests a disconnection or malfunction of the encoder, or incorrect detection settings.

Additional Steps

Steps 1–2 are listed in Priority Fix.

1. 3

   Increase the 'Creep Speed Setting' (P015) to a slightly higher frequency if the motor struggles to start under load.

2. 4

   Verify the encoder's functionality and output signal using a multimeter or oscilloscope.
